抄録

Soon after the eruption of Akita-Komagatake Volcano had taken place in 1970, the geochemical survey was carried out with the aim at elucidating the present status of the hot springs, rivers and lakes in the vicinity of the volcano. The results of the investigation are summarized as follows : 1. Judging from the chemical constituents of the waters, hot springs in this region are classified into the following two groups ; Chloride ion type : Kunimi (1, 2) and Tsuru-no-yu (5, 6) Sulfate ion type : Mizusawa (3, 4), Ganiba (7), Magoroku (8), Kuro-yu (9), Okama (10) and Ipponmatsu (11) 2. The hot springs in the mid-slope of the volcano is characterized by the high content of dissolved minerals as compared with hot springs in Nyuto spa. 3. From the geochemical point of view, Okama hot sping is the active center of hot springs and fumaroles in Nyuto spa. 4. The quality of waters including hot springs, lakes and rivers in the volcanic region is not influenced by the present eruption.
